wnwow CLEANING SEAT Filed Jan. 6, 1937 INVENTOR Gmeaz Lava 2' ATTORNEY Patented Sept. 12, 1939 UNITED STATES PATENT OFFICE Application January 6,

18 Claims.

This invention relates to window seats. More particularly, this invention relates to the type of window seat adapted for use in cleaning the outside of windows in apartment houses and private homes.

One of the objects of my invention is to provide a novel and simplified construction of a folding window cleaning seat of the character described which will automatically adjust itself to slight variations in window sill sizes and which at the same time shall enable a person to clean the windows from the outside thereof with a high degree of safety.

Another object of my invention is to provide a folding window cleaning seat of the character described having novel and simple means of attachment whereby it is adapted for use in connection with different sizes of window sills, which shall comprise relatively few and simple parts, which shall be easy to assemble, relatively inexpensive to manufacture, sturdy and yet light in construction, and which at the same time shall operate with a high degree of efficiency and safety.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible embodiments of this invention,

Fig. 1 is a side elevational view of a window cleaning seat embodying my invention and shown operatively attached to a window sill;

Fig. 2 is a rear elevational view of the Fig. 1 form of device;

Fig. 3 is a sectional View taken substantially on the line 33 of Fig. 1;

Fig. 4 is a perspective View of the window cleaning seat illustrated in Fig. 1 but with the window sill omitted; and

Fig. 5 is a side elevational view showing my window seat detached from the window sill and in collapsed or folded position, suitable for storage.

Referring now in detail to Figs. 1 to 4 of the drawing, there is disclosed a window cleaning seat in open, operative position, constructed in accordance with my invention. Said window cleaning seat comprises a base or seat portion In which may be of wood, and provided with a 1937, Serial N0. 119,173

pair of metallic reinforcing members or brackets H at opposite ends thereof. The seat l may be made of wood, or, if desired, the entire assembly of the seat [0 and members H may be of unitary metallic construction. Pivotally attached to the ends of the seat It) by means of pivots ill at a point adjacent the rear longitudinal edge of said seat I0, is an inverted U-shaped frame adapted to serve as the back rest B for the window cleaning seat. The back rest B may comprise a pair of arms l interconnected at the top by a cross member I! which may be integral with said arms IS. The back rest B is held in proper position and counter-clockwise movement thereof is limited by the provision of lugs l9 extending inwardly of the lower free ends of the arms I 5. The said extended portions l9 are so designed that when the back B is pivotally moved in a counter-clockwise direction a predetermined amount, the said lugs will abut the underside of the brackets I l and thus prevent further counterclockwise movement of the back B.

Pivotally attached to the ends of the seat In by means of a pivot 2| disposed intermediate the longitudinal edges of the seat It], are a pair of aligned side supporting members 20. When the window seat is in operative position as shown in the drawing, the side supports are disposed substantially perpendicular to the horizontal plane of the seat Ill.

The side supports are designed to hold the window cleaning seat in rigid and safe attachment to the inside window sill, and, therefore, means are provided to limit the clockwise rotational movement of said supports 20. Such means comprise portions 22 extending inwardly from said supports, said lugs being designed to abut the underside of the seat in to thus limit the clockwise pivotal movement of said supports 20 about the pivots 2|. Pivotally attached adjacent the upper ends of the members 20 by means of pivots 26 are a pair of adjustable arms comprising the interconnected members and 21. To adjustably interconnect the members 25 and 21, they are each provided with a plurality of spaced apertures 3|, the apertures in the members 25 being adapted to register with the apertures 3| in the members 21. The members 25 and 21 are held together by any suitable fastening means, such as bolts 32, passing through the pairs of registered apertures 3| and held by wing nuts 32a. The members 21 are provided at their outer ends with hooked portions 28 designed to grip and hold the rounded edge 30 of the inside window sill, as clearly shown in Fig. 1.

To provide additional support for the members 20 and at the same time to facilitate the folding or collapsing of the window seat, there is provided a pair of links 35, each of said links being pivotally fastened at one end thereof to the upper end of a support 20 by means of the pivot 26, while the other end thereof is provided with an elongated slot 36 designed to receive therein an enlarged headed pin 31 fixed to the arm 45. When the back B is in proper opera.- tive position, the pins 3'! will contact the end of the slots 36 and the links will thus aid the supports 20 in overcoming the pulling strain exerted by the adjustable arms 25, 21.

To prevent slipping of the seat 10 on the outer window sill and to provide a safe and rigid grip for the adjustable arms 25, 21 and the hooks 28, I have provided a pair of downwardly projecting rigid members 38 rigidly attached to and having an inclined surface 39 thereof projecting slightly below the lower edges of the brackets H. The members 38 spaced from the inner longitudinal edge of the seat lila predetermined distance, are designed to contact and abut the outer edge of the outside window sill, the inclined surface 39 being adapted to overlie a portion of the top surface of the outer window sill, and the downwardly projecting portions of the members 38 being adapted to overlie a portion of the outer edge of said outer window sill. It is thus seen from Fig. 1 of the drawing that when the window seat is placed in proper position, such as shown, with the hook portions 28 engaging the molding edge 30 and with the arms 25 and 2! properly adjusted as to distance, the members 38 will firmly contact the outer edge of the outer window sill, and since the supports 20 will be prevented from further rotation by the lugs 22 and the slotted links 35, it is seen that the entire assembly will be safely and firmly held in position.

It is noted that the seat iii will be prevented from being raised to dislodge the members 38 from their position, due to the weight of the person seated thereon.

My novel construction is so designed that when the hooked portions 28 are in engagement with the inside window sill and the seat Hl properly positioned, the said seat l0 will pivotally rock about the pivots 26. The result of this construc tion is such that the window cleaning seat oonistructed in accordance with my invention is. adapted to automatically adjust itself to slight variations in distances between the inside and outside edges of the window sill of diiferent windows.

My window cleaning seat as above described is designed to be folded into a compact unit for storage, as illustrated in Fig. 5 of the drawing. To fold the seat into the position as shown in said Fig. 5, it is merely necessary to slightly loosen the wing nuts 32m, and then fold the members 21 to lie adjacent the members 25. The links 35 are then slidably moved backwardly to cause the supports 20 to rotate on the pivots 2| until they are caused to be adjacent the members 25 and 21. After this has been done the back B is pivotally swung down to lie adjacent the top surface of the seat Iii.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth,

it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
